What records should I keep for Monero mining taxes?

Keep a dated record of your mining rewards, their value in your local currency, your mining costs, and what happens when you sell, spend, or exchange the XMR. Save the original payout reports and receipts, not just your totals. Tax rules vary by country, so ask a local tax professional when rewards count as income and which costs you can claim.

Record each reward and payout

Keep a spreadsheet with one row for each reward or payout. Include:

• The date, time, and time zone.
• The amount of XMR you received.
• The mining service or pool that paid you. A pool combines miners’ work and shares the rewards.
• The receiving wallet and transaction ID, the reference identifying the transfer.
• Any fees shown.
• The reward’s value in your local currency and the price source you used.

Keep separate records for rewards credited to your mining account and payouts sent to your wallet. An unpaid account balance is not necessarily treated the same as coins you can access. Whether income arises at credit, payout, or another point depends on local rules.

If you receive a newly mined block reward directly, note when it becomes spendable. Those coins are locked for 60 blocks. A pool payout is generally an ordinary transfer, so do not automatically apply that lock to it.

Save evidence of the currency value

Your wallet may show how much XMR arrived without showing its value for tax purposes. Save the exchange price or historical price record used for each valuation, including its timestamp and currency.

If your price source quotes XMR in a foreign currency, keep the exchange rate used to convert that value into your tax-reporting currency.

Use a consistent valuation method that is accepted where you live. Do not assume today’s price, an annual average, or a dashboard estimate is suitable. For frequent small rewards, ask whether your local rules allow daily summaries, and keep the underlying records even if they do.

Track sales, spending, and transfers

Mining income and a later sale can create separate tax calculations. For every sale, exchange, or purchase made with XMR, record:

• The date and amount of XMR disposed of.
• The money, cryptocurrency, or goods received, with their local-currency value.
• Trading and transaction fees.
• The original acquisition record and its cost basis—the value assigned to those coins for calculating a later gain or loss.

The value already counted as mining income commonly helps establish cost basis, but confirm your local treatment.

Label transfers between wallets you own clearly. They generally are not sales, and good labels help prevent counting the same coins as fresh income twice.

Keep costs and private backups

Save hardware invoices, mining-related service fees, and electricity bills. For electricity estimates, record measured power use, mining hours, and the rate charged. If you also use the device personally, document how you divided that use. A receipt does not automatically make a cost deductible.

Export payout histories regularly, especially before closing an account. Monero’s privacy features mean a public blockchain explorer cannot provide a complete, readable history of your wallet activity.

Back up your spreadsheet and supporting files securely. Never put your recovery phrase or private spending keys in tax records. Ask how long records must be retained locally; acquisition evidence may be needed until years after you sell.

The bottom line

Keep enough evidence to explain where each reward came from, how you valued it, and what happened to it afterward. Regular exports and clear transfer labels will make tax preparation much easier.
